This may be out there somewhere, but I didn't find an answer. It's a quick question, inspired by looking at a load of empty White Labs vials and a desire to make some slopes. I have the means to autoclave in my pressure cooker or pressure canner. Are the vials reusable for this purpose?

I've had the same thought, but after pulling some warped and shriveled PETE containers out of my dishwasher, I've been afraid of melting vials to the bottom of my pressure cooker. Besides I can "borrow" glass culture tubes from work.

If you're talking about autoclaving the tubes, yeah, they'll melt. If you're just talking about adding autoclaved agar to them, it should be fine as long as you let it cool sufficiently before you add it to the tube.

Those are nice and would work really well. Quite a bit more pricey than the others, but in more manageable quantities. I mean, it's nice to get 1000 for $20, but then you have 1000 tubes . . .

...only giving rise to further comments about how much brewing related equipment is in the house.

I'd be more worried about the nosy neighbor who thinks I'm making crack.

Could always tell the wife they are for vodka shooters at her next party... and the party after that... and the party after that.... Hmm if we are going to throw that many parties, I had better brew some more beer!!
